Metrology for Home Assistant

Metrology is a practical series of app customizations and redesigns aimed at bringing a bold, clear, and consistent user experience to various Windows and Android apps. Its design language is based on Metro and Fluent design systems pioneered by Microsoft Design since the 2010s.

Home Assistant is an open source home automation server that integrates nearly 2000 existing IoT services into one powerful, private, and unified user interface. It is perfect to run on a Raspberry Pi or a local server.

Here is a collection of themes, tweaks, and template buttons to make your Home Assistant look bold, modern, and clean.

How to Install the Theme

If you have HACS, you probably already know what you are doing. You can search for this theme and install it there. If you don't have HACS, here are the steps:

Prerequisites

• Some way to upload files to your HA server, e.g. Visual Studio Code or Samba add-ons
• card-mod

Installation

1. If you are new to Home Assistant and its themes, you first need to add this in your configuration.yaml file:

frontend:
  themes: !include_dir_merge_named themes

2. Create a new folder named themes under /config.
3. Copy metro.yaml to /config/themes.
4. (Optional if you want Segoe UI on non-Windows devices) Copy style.css and the .ttf font files in the /www folder to /config/www.

• If you are using the Lovelace Dashboard not in YAML mode, go to your Home Assistant Settings -> Dashboards -> Resources and then add /local/style.css as a Stylesheet. (Note: It might look strange that you had copied the files to /www but here you typed /local, but HA will handle the path redirection for you so no worries.)
• If you are using it in YAML mode, add the following to your lovelace resources section:

    lovelace:
      mode: yaml
      resources:
        - url: /local/style.css
          type: css
  

5. Restart Home Assistant to apply the changes. Once restarted, go to your Profile page, which is the button where your avatar is at the bottom left.

6. Under Themes, choose the color you like for the Metro themes.
7. Pick Auto, Light, or Dark Mode for the theme.

Segoe UI font is optional if you are already using Windows. If you are not using Home Assistant, you can download the fonts here and upload them along with style.css to your /config/www folder.

Live Tile Templates

This is for advanced users only. If you don't know how to edit YAML, this will be rather difficult.

TBD. Includes button-card templates in the form of Live Tiles. Watch this repo for updates.
